To second Paul's suggestion, usually, if the regex is not immediately
obvious, its probably better to look into parsing modules, pyparsing
being one of the most accessible modules (to me, anyways)--and well
worth learning.
However, in complicated applications, regex is usually still fun and
valuable as an intellectual exercise.
